A pipetting device () for an apparatus for processing a sample or reagent is disclosed. The pipetting device () comprises a coupling mechanism, wherein the coupling mechanism comprises at least a first coupling unit () adapted to be coupled to a first pipetting tip () and a second coupling unit () adapted to be coupled to a second pipetting tip (), and a selection element () for selectively allowing a coupling of the first coupling unit () to or releasing the first coupling unit () from the first pipetting tip () and for selectively allowing a coupling of the second coupling unit to or releasing the second coupling unit () from the second pipetting tip (). The selection element () is mechanically coupled to the first coupling unit () and the second coupling unit (). Further, an apparatus () for processing a sample or reagent and a method for pipetting a sample or reagent are disclosed.

A device and a method for the adjustment of a temperature of a liquid which is contained in one or more sample vessels are specified, a control unit and a temperature adjustment unit being provided, which acts on the liquid contained in the sample vessels. Furthermore, the control unit is operatively connected to the temperature adjustment unit. The liquid to be analyzed contains absorption elements in order to accelerate the temperature adjustment in the liquid to be analyzed.
